Does anyone know what plant this is?

[JimineyC]

It just seeded itself into a plant pot and has grown vigorously since. I like it but haven't been able to identify it as yet. Any ideas?

Thanks

Hi Jiminey. Looks like some sort of Euphorbia or Spurge?
Someone else will be along soon with a better suggestion!!

I was thinking Sedum because of the fleshy looking leaves.

I think sedum, too - we have it everywhere that is dry, pretty little yellow flowers.

I'm thinking Sedum, too - although mine are more grey-coloured.
